Greg Louganis

Diver Greg Louganis hasn't been involved with the Olympics for 20 years, but he returns today as a coach and mentor for the U.S. Diving Team.

The significance of this goes far deeper than the 1988 gold medalist's triumphant return to the international stage -- Louganis became a lightning rod of controversy when he came out as gay and HIV-positive after the Seoul Olympics.

Film producer Will Sweeney is determined to tell Louganis' incredible story:

There are so many people around the United States -- and the world -- who have very fond memories of Greg -- cheering for him after he hit his head, how his autobiography made it okay for them them come out, how he helped Americans put a face to HIV. But there is a whole generation of young people who haven't heard about Greg.

Sweeney's and fellow producer Cheryl Furjanic's new documentary, Back On Board,will "address issues that are important to (Louganis) -- combating bullying and homophobia and the need to support elite athletes that move on after their athletic careers are over."

The pair have raised more than $14,000 toward their Kickstarter goal of $50,000, with donations ending in 28 days.
